Mac Preview is the default photo and PDF viewing program built into every Apple computer. It allows users to bypass using Adobe Acrobat (or, Photo Viewer on Windows computers).
Originally designed to simply view documents, Mac Preview offers a variety options for making minor edits. If you use a Mac computer and don't think of yourself as particularly "graphic design-savvy," check out these easy-to-use editing features of Mac Preview:
- Color Adjustments
- Crop Functions
This blog post will demonstrate how you can take advantage of each of these features of Mac Preview using cute cat photos ... because the Internet really exists for us to all look at cats, right?
Note: Before making edits to photos, it is good practice to save a copy of the original photo so you can always come back to it if needed. Learn more about version control.
After opening my three adorable cat photos, I can see my preview window has all three photos in the left sidebar, and I can view one image at a time in the main viewing area.
Next, in the top navigation, click Tools > Adjust Size. By typing in a new width, you can resize the images to a desired width. Additionally, you can change the resolution to something more web-friendly. Typically, high-resolution photos are 300 pixels per inch, while photos on the web are set to 72 pixels per inch. Less pixels means less data, which means smaller files. Smaller files online are important because they help your webpages load faster.
Notice that the image size at the bottom has been drastically reduced by changing the image size. After making my changes, click "OK" and your edited images are changed. Save your files and your images will be permanently changed to this smaller version.
Tip: If you do this and still find that your images are too large, check out Tiny PNG for an easy, free, online resource for image compression.
To access annotations, in the top navigation, click Tools > Annotations >. You'll see a number of options appear. Choose any of those options, and the entire annotations toolbar will appears. You can make a number of enhancements with text, lines, arrows, and even draw on it freehand.
Crop functionsWhen you first open a photo in Mac Preview, the cursor is a crosshair that you can drag to make a rectangular shape. drag, make your selection, and choose Tools > Crop to remove everything except your selected area. As a bonus, you can see the dimensions of the selected area, which can help if you know you want a specific-sized photo.
Choose File > Export and you will see a clear set of options for getting your file in the format you need.
The export function is very helpful for converting in- and out-of-PDFs, and it's also useful for saving a cropped photo as a PNG to style it with no background (just like our TBH Creative headshots).
